## [v0.3.0] - 2018-09-23 - YANKED

### Added

  maximum allowed log level.

  takes `&mut self`.

### Removed

- [breaking-change] The `set_global_logger!` macro has been removed in favor of
  the `global_logger` attribute.

  individually enable / disable log levels has been removed in favor of Cargo
  features.

## [v0.2.0] - 2017-07-06

### Added

- Support for global logging: a `set_global_logger!` macro was added, and the
  `$logger` argument is now optional in all the logging macros.
